Subject: [PATCH 1/4] Input: sparse-keymap - send sync event for KE_SW/KW_VSW

Sync events are sent by sparse_keymap_report_entry for normal KEY_*
events, and are generated by several drivers after generating
SW_* events, so sparse_keymap_report_entry should do the same.

Without the sync, events are accumulated in the kernel.

Currently, no driver uses sparse-keymap for SW_* events, but
it is required for the intel-vbtn platform driver to generate
SW_TABLET_MODE events.
